Use for your Race Face cinch chainrings

  • Familiarity: I've used it once or twice and have initial impressions

While this tool does do it's job for Shimano ISIS bottom brackets, I bought it to swap chainrings on my Race Face Cinch (direct mount chainring) crankset. I bought this one over the Park tool version because I can use it with a 1/2in driver, just like my Pedros cassette tool, whereas you need a crescent wrench with the Park version.

Required for Raceface chain ring swap

  • Familiarity: I've used it several times

Critical little tool if you want to open up your chain ring on the Raceface Next SL and clean it, swap it out, etc. I was getting some creakage out of that area on my Santa Cruz Tallboy and couldn't solve the problem until I was able to open up and clean out the crank set system with this tool.

It works

    If you still have a cartridge splined BB like the Shimano UN 54 or Octalink (or ISIS...but I have no idea why you'd still have that), this tool is necessary. It works. It's nice that it adapts to a 1/2" driver so you can use a ratchet or a big breaker bar for the times when the BB gets stuck. I don't use mine so much anymore because I don't really have any of those BBs, but I keep it around for when I need to work on my teammates' or friends' bikes.

    will this work on a shamano bottom...

    will this work on a shamano bottom bracket?

    Yes, this will work with any Shimano ISIS 20-tooth splined bottom brackets.
